IMPROVEMENT IN HEATERS.

Specification forming part of Letters Patent No. 176,4 I6, dated April18, 1876 application led April 9, 1874.

To all rwhom it may concern:

Beit known that I, JESSE REYNOLDS, of Philadelphia, Pennsylvania, haveinvented certain Improvements in Heaters, of which the following is aspecification:

The object of my invention is to construct a heater in which to burnsoft or bituminous coal Vwith the best results, an object which I attainin the manner illustrated in the vertical section Figure l of theaccompanying drawing, and in the sectional plans Figs. 2 and 3, andtransverse vertical section, Fig. 4.

The outer casing A, composing .the main body of the heater, is of theoval sectional form shown in Fig. 3. This casing A is made of sheet-ironplates, and is surlnounted with a cover, B, of the concave-convex form,represented in Figs. 1 and 4.

The cover is made of any appropriate number of sheet-iron plates-threein the present instance-the edges of the adjoining plates being flanged,and these anges being riveted together, thus forming permanent girders,which serve to strengthen the cover, the latter, as thus constructed,being an especial feature of my invention.

The heat generated by a soft-coal fire is intense, and an ordinary flattop of' a heater, if made of reasonable thickness, could not retain itssha-pe when subjected tothis heat; but comparatively thin plates may beused in constructing the concavo-convex cover, providing it isstrengthened by the riveted flanges a a, in the manner illustrated anddescribed.

Below the main body A of the heater is the casing D, containing thelire-place E and ashbox F, the tire-place being of the oblong formrepresented in the sectional plan, Fig. 3, and situated near the frontof the oval casing A, inclosing the combustion-chamber Gr, the outlet Hfrom which is situated at the rear of the casing near the roof.

After many practical tests I have ascertained that this combination ofoblong tireplace, oval combustion-chamber, and outlet, situated inrespect to each other, as shown, is the best for effecting a thoroughcombustion of the soft coal, and for 'imparting to the casing A thegreatest heat.

Another advantage of the oval casing is the facility and economy withwhich it can be made of comparatively light material, for it hassufiicient inherent strength to retain its shape in the absence ofcorner angle-irons.

As the rear of the combustion-chamber is subjected to intense heat, Iline it with refractory tiles in the manner illustrated in Fig. 4. Thetiles e are carried upward against the interior ofthe casing A, a shortdistance above and on each side of the tire-place, and these tiles meetthe rear tiles f, which are made to conform to the shape of the casing,and are carried upward in steps to the roof, the upper tiles tting intorecesses in those below, so that the Whole may be retained in theirproper positions.

Owing to the concentration of the ignited products of combustion at theoutlet H, which formspthe commnication between the combustion-chamberand the radiator I, part of which is shown in Fig. l, this outlet-branchis subjected to intense heat; hence I line the metal tube with a shortpipe of fire-clay or other refractory material.

The grate, doorway for the introduction ot' the fuel, doors, ash-pit,and opening through which air for supporting combustion is admitted,-are of the ordinary character, and will require no explanation.

I do not claim, broadly, the protection of the casing of thecombustion-chamber with tiles or fire-brick, as this forms the subjectof a separate application which I am about to make for a patent.

I claim as my inventionl. The combination, in a heater, of an ovalcombustion-chamber, G, a fire-place, E, communicating with the lowerpart of the said chamber at one end, and an outlet, H, leading from theopposite end of the chamber, near the top, all as and for the purposedescribed.

2. rIhe concavo-convex cover orV roof of the combustion-chamber, made ofplates flanged andriveted to form strengthenilig-girders, as described.

3. The combination, with the tire-place and combustion-chamber, ofrefractory tiles arranged in courses at the rear end of the chamber,each course being recessed to receive the course above it, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

JESSE REYNOLDS.
